PHYSÂ 425. Geometric and Physical Optics. (4).
We will study the fundamental properties of light, explore optical phenomena theoretically and in laboratory setting. We will start the study of light with the Fermat principle. Matrix element ray optical methods will allow students to resolve the geometry of optical systems through computer simulations. This followed by light's wave phenomena including designs for optical interferometers. Gaussian laser beams will be introduced. Fourier optical methods will be examined and applied to diffraction phenomena, and ultimately applied to phase retrieval in diffraction imaging. The quantum mechanical nature of light will be introduced, followed by laser systems and semiconductor light detection devices. In the laboratory students will build, and study, applied systems such as laser interferometers, Fabry-Perot spectrometers, external cavity laser designs, Fourier optical setups, laser ring gyroscopes, laser tweezer optical traps and quantum optics opto-electronics systems. Prerequisites: MATH-261, MATH-265, and PHYS-212.
